Specification of Letters Patent.

PNEUMATIC TIRE.

Fatented Nov. is, ten.

Application filed-April 4, 1908. Serial No. 425,258.

To allughom it may concern:

Be it known that I, WILLIAM E. ANDREW,

a citizen of the United States, residing at Atlantic Highlands, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improve- -ments in'PneuInatic Tires; andl do here by declare the following to,be a'full, clear, and exact description of the invention, such as' will enable others skilled in the art to which it-appertains to make and use the same;

My invention relates to improvements in pneumatic tires, and has for its object to provide a tire of the olencher type of improved form, together with novel instrumentalities for attaching and holding the tire in place on the rim of the wheel.

One of the objects of my invention is to afi'ord means whereby the air-tube may readily be removed and replaced, when it is necessary to repair the same, all of which may, be accomplished with the greatest ease.

Another object of myinvention is to pro vide against rim-cutting and blowing out of the tire, the parts which effect this servingualso to prevent sidewise deflation of the tire, and to give strength and durability to the parts.

Still a further object contemplated by my improvement is to prevent serious damage tothe tire, owing to deflation of the air-tube, in the event that the'same becomes punctured.

A further object contemplated by my improvement is to construct a tire and apply it to a wheel in such a manner that the pressure of the air within the air-tube will be confined above the clencher grooves of the shoe, and that the iiir-tuhe will bear equally upon inward-projecting bearings of the shoe 4 base-flanges or the shoe also and being held in in view, my invention in its preferred form, includes the novel construction. and combination of parts hereinafter described in detail, and set forth in the annexed claims.

In the accompanying drawings, forming a part of this specification, and to be read in conjunction therewith, Figure I is a perspective view, partly in section, showing the rim of a wheel equipped with my improved form of pneumatic tire, and the means for attaching the same; Fig. II is a vertical sectional view of the rim and tire, the inner airtube being shown partially removed. and with some slight modifications; Fig. III is 'a view similar to Fig. II, with all the parts secured in position.

Referring more particularly to the draw-' ings, in which like characters of reference refer to corresponding parts in the several views, A designates the telly of a wheel, and a is a metallic plate secured upon the telly by bolts 0?, or similar suitable attaching devices. A ring B is removably secured above the plate a by means of bolts b, and oqnstitutes a projection on the folly plate adapted to be engaged at its sides and top by flanges of the shoe C. The shoe C is provided in-- teriorly with an inward projecting cylindrical abutment E and engage the top of ring B, should the inner tube collapse, as aresult of puncture. The abutment E thus forms a support for the shoe and by preventing further collapse, enables the tire to be used even though punctured, without causing serious damage.

F are flanges or overlapping projections formed on the inside of the shoe, and

adapted to engage the top of ring. B, as

shown-clearly in Fig. 1. Embedded in the projections F are strips 0 of any suitable arranged to move toward hard but not necessarily non-yielding substances, giving strength and rigidity to the overlapping parts, and tending to hold the shoe in fixed position, especially when the strain is great as on turning a corner. The have strips (5 embedded therein, of hard but not necessarilynon-yielding material, said basefianges lying against the sides of ring B, place by the clamping ,or clencher ringsG. By reason of the taper of the sides of ring B, the overlapping flanges or projections F, and the engagement of rings G with the base-flanges at points below theouter face of ring B, a per feet rigid fastening is obtained and a solid bearing is afforded for all of the cooperating parts, and in such a manner as to hold them tight, and at the same time protectthem.

The clamping rings G are provided with inward-extending flanges e which engage the top of the t'elly and retaining lugs K by which they are attached to the side of the telly, in any desirable Way as by bolts 9 and nuts 71. The bolts 7 before-mentioned are preferably squared through their body portion, as shown in Fig. III, the opening through the telly being correspondingly squared; and the nuts 11-, secured to said bolts 9, are provided With curved faces to engage correspondingly curved depressions in the lugs IQ By this construction, it will be seen that the nut need only be placed on the end of the bolt and turned, in order to draw the bolt through the flly, and secure the parts tightly, such resultbeing obtained by the cooperation between the curved faces of the nuts and the similarlycurved depressions in the clamping ring. In the construction shown in Fig. IL I omit the curved faces of the clamping ring and nuts, and employ in lieu thereof a'nut having a collar (23 adapted to he received by the opening in the clamping ring on one side, the usual form of nut being employed on the remaining side.

H is the inner air-tube havinga canvas strip I upon its bottom face to engage and bear on the ring B and projections F.

It will be obvious that While I have shown my invention in a particularembodiment, various changes and modifications may be made Without departing materially from the spirit and scope of my present improvement.

\Vhat I desire to secure by Letters-Patent, and claim, is

1. In a pneumatic tire, the combination tending over the top of said outwai'd-pro strips of strengthening majecting portion.

1n the shoe ildJflCOIlt to said tcrial embedded flanges, and means for holding the shoe in position. I

2. In a pneumatic tire, the combination with aivhecl, of a detachable outward-projecting' portion surroundingthe wheel and provided with tapering sides. a shoe embracing said't-apering sides of the outward projecting portion. flanges on the inner wall. of the shoe extending over the top of said outward projecting portion, said shoe having a groove in its outer Wall, and movable clamps engaging the aforesaid groove. said clamps bearing on the top'of the telly and extending downward inconta'ct with the sides of the folly. and bolts for scouring the clamps to the felly.

In testimony'whereof, I alliX my sigma-- ture, in the presence of two subscril'iing witnesses.
